(With an added unfortunate one minute battery changing pause.)
You are increasingly made of computers (pacemakers, hearing aids, prostheses), you are increasingly inhabiting an internet of things (cars, planes, buildings), and that's potentially pretty bad news. The model for regulating computers is to insist that they be somehow constrained so that they can't do undesirable things, but we don't actually know how to do this - the closest we come is making computers that have supervisory processes that spy on you, that you can't shut down, and that every conceivable kind of bad guy could use to come after you.
